As individual tools, both Android zero-touch enrollment and dual-SIM devices offer a wealth of business benefits. But until recently, the two IMEI numbers - one for each SIM card - in a dual-SIM device meant integrating dual-SIM with zero-touch was unreliable and dependent on SIM configuration.
The good news: we’ve enhanced dual-SIM support in zero-touch, improving the reliability of dual-SIM enrollment, and simplifying management.
What does this mean?
This improved integration is a step forward, and addresses the known issues some users have previously experienced when provisioning dual-SIM devices with zero-touch. It means dual-SIM devices don’t need to be registered as two separate devices to be reliably managed. It also minimises the risk of devices being missed during provisioning and getting stuck in a reset loop, or randomly undergoing factory reset.
There is no action required to activate this fix, and you’ll only be visibly impacted if you’ve experienced the issues above. Otherwise, we’d recommend you continue to follow the steps below as best practice.
Going forward, we’ll be looking to streamline the process of registering dual-SIM devices further, but for now...
Here's how it works:
Lead with the lowest IMEI:
For zero-touch to recognise and configure both SIM profiles, the device initially needs to be registered with the numerically lowest IMEI. For example, if the two IMEI numbers are 000000000000001 and 00000000 0000002, you would register the first.
Once the device is powered-on and set up it will download the latest Google Play services. Zero-touch will then detect the device, register its serial number, and prompt a factory reset.
The next time you set up your device, both SIM profiles will be provisioned through zero-touch, applying your pre-configured settings and apps. Cue smooth sailing.
Tips for a smooth two-step
Communicate with your reseller: Make sure they understand the importance of registering with the lowest IMEI for dual-SIM devices.
Test, test, test: When integrating dual-SIM devices with zero-touch, begin with a test batch to identify and troubleshoot any hiccups. You may also wish to check this documentation for any known issues.
Documentation is key: Clearly document the specific steps for dual-SIM zero-touch deployment so users know what to expect when setting up, especially as a device factory reset is currently required.
